From 0e16297461264b3ea8f7282d1195cf53aa8a707c Mon Sep 17 00:00:00 2001 From: Andreas Färber Date: Mon, 14 Jul 2014 17:38:18 +0200 Subject: libqos: Fix PC PCI endianness glitches MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The libqos implementation of io_read{b,w,l} and io_write{b,w,l} hooks was relying on qtest_mem{read,write}() respectively. With d81d410 (usb: improve ehci/uhci test) this resulted in assertion failures on ppc hosts: ERROR:tests/usb-hcd-ehci-test.c:78:ehci_port_test: assertion failed: ((value & mask) == (expect & mask)) ERROR:tests/usb-hcd-ehci-test.c:128:pci_uhci_port_2: assertion failed: (pcibus != NULL) ERROR:tests/usb-hcd-ehci-test.c:150:pci_ehci_port_2: assertion failed: (pcibus != NULL) qtest_read{b,w,l,q}() and qtest_write{b,w,l,q}() had been introduced as endian-safe replacement for qtest_mem{read,write}() in I2C in 872536b (qtest: Add MMIO support). Use them for PCI as well.
